How to combine JPG images and PDF files into one PDF

Use the supported mixed-file workflow

Merge PDF accepts PDF, JPG, JPEG, and PNG inputs in one job. Every image becomes one PDF page at its position in the ordered file list.

Image pages use their pixel dimensions at 96 pixels per inch. Use JPG to PDF first only when custom page size or margin options are needed.

1. Open Merge PDF and add the PDFs and image files together.
2. Arrange the complete PDFs and individual image pages in the required order.
3. Merge the files, download the result, and verify all page transitions.

What this workflow helps you do

This Guide answers a focused Merge PDF task and connects the explanation directly to the working browser tool.

Add PDF, JPG, JPEG, and PNG files to one merge job, arrange them together, and create the combined PDF.

Plan the task in Merge PDF

Combine complete PDFs and individual JPG or PNG images into one document. Reorder the files, check the page previews, and rotate individual pages before downloading the merged copy. Each image becomes one page; to interleave pages from different PDFs, use Organize PDF instead.

People searching for a PDF merger usually need one finished document, not another complicated workflow. PDFKaka lets you add complete PDFs and individual JPG or PNG images, inspect the output pages, arrange the file order, rotate pages when necessary, and create one combined PDF without sending the source files to a remote service.

1. Merge multiple PDF files into one document. Add the PDFs together, place them in the required sequence, and review the page thumbnails before processing. The original files remain unchanged, so you can correct the order and create another copy if needed.
2. Merge PDF pages without reducing quality. The merger copies PDF pages into the new document instead of converting every page into a screenshot. That avoids unnecessary image recompression and preserves the visible source-page quality.
3. Combine PDF, JPG, and PNG in one workflow. Add JPG or PNG images directly alongside PDF files. Each image becomes one PDF page at 96 pixels per inch, while pages already inside each PDF keep their existing order.

Follow the focused browser workflow

Add PDF, JPG, JPEG, and PNG files to one merge job, arrange them together, and create the combined PDF.

Use Merge PDF for the supported operation, keep the source unchanged, and make one reviewed output rather than repeatedly processing an already changed copy.

1. Prepare a supported source file.
2. Choose only the settings needed for the task.
3. Download and review the completed result.

Settings and limitations to check

Can I merge PDF files online for free? Yes. Add supported PDF, JPG, or PNG files, arrange them, and download one combined document without creating an account.

Are my PDFs uploaded while they are merged? No. The current merger reads and combines the documents in this browser, so their contents do not need to be uploaded to PDFKaka.

Should I use Merge PDF or Organize PDF? Use Merge PDF when complete documents are already correct internally. Use Organize PDF when individual pages from several PDFs must be moved, rotated, or removed.

1. Use only the settings needed for the required result.
2. Keep the source file available for comparison.
3. Do not rely on an unsupported exact-size, fidelity, or security promise.

Review the completed file

Check that image pages use the expected size and appear at the correct point in the merged document.

Open the downloaded result in a separate viewer, inspect important pages or details, and repeat the workflow with adjusted settings if the output is not suitable.

1. Confirm the expected file type and page count.
2. Check important text, images, order, and orientation.
3. Share or submit only the reviewed copy.
